BSP742R

BSP742R Description

The BSP742R from Infineon Technologies is a high-side power switch belonging to the Classic PROFET series, designed for automotive and industrial applications requiring robust power distribution. This AEC-Q100 qualified device operates within a 5V to 34V input range, delivering a maximum output current of 0.4A (min) with a low on-resistance of 250mΩ (max 350mΩ). Packaged in an 8-pin DSO (Tape and Reel), it features surface-mount (SMD/SMT) compatibility, making it ideal for space-constrained designs. With a power dissipation of 1.5W and current limiting at 1.2A, it ensures reliable protection against overloads and short circuits. Its EU RoHS compliance and EAR99 ECCN classification further enhance its suitability for global markets.
